Son of a lawyer (avocat), Defferre studied at the Faculty of Law in Aix-en-Provence and practiced law from 1931. During World War II he served in the resistance and was briefly mayor of Marseille near war’s end. He was deputy to the National Assembly almost continuously from 1945 until his death. He favoured independence for France’s overseas territories, including Algeria. When Charles de Gaulle came to power in 1958, Defferre was without a parliamentary seat until 1962, when he returned and rallied the Socialist Party’s opposition to de Gaulle’s presidency. Standing as the Socialist presidential candidate in 1969, however, Defferre received only 5 percent of the vote.

His most formidable power base, however, was in the town hall at Marseille, where for 33 years he managed to hold off the challenge from the right and presided over the creation of a modern city, built up its social and cultural amenities, and tried to ameliorate the city’s problems of finance, housing, and influx of emigrants from Algeria in 1962.
